JBL-patented Plus One® woofer cone

The JBL-only Plus One® woofer cone (patent #7,548,631 B2) is exceptionally stiff, lightweight, and has up to 25% more active surface area than you’ll ever find on competing models of the same size. You get an audible increase in bass output and efficiency.

Home theater-quality tweeter

Listen loud. It’s a high-bandwidth, edge-driven dome tweeter with a large voice coil, like high-end home audio loudspeakers. My-Ti™ (a proprietary Mylar-titanium composite) delivers great power handling. Extended high frequencies. And seamless integration with the woofer.

Exceptional venting for increased power handling

Woofer motor structures heat up during use, causing distortion, or power compression that reduces music’s dynamic range, robbing the sound of realism. JBL uses vented motor structures and polepieces that get rid of more heat to deliver more serious bang.

More true sound from crossover network

With a computer-optimized, voice-matched, passive crossover network the GTO8608C creates a smooth transition between the woofer and tweeter. Midrange vocals sound so natural and lifelike you think you the artist were right in the car with you.

True 4-ohm topology performance

For the most powerful performance, the GTO8608C makes the best use of any amplifier by providing an optimum 2-ohm load. It uses a lower-impedance voice coil than a typical speaker to extract the most possible from all amplifiers engineered to drive loads of 4 ohms or less.

Tweeter Control

The JBL GTO8608C has a tweeter high-cut filter on the crossover that allows you to attenuate the tweeter by -6dB to optimize performance and optimize blend with the the mid/woofer based on installation location.Personal, tweeter level control.

Outstanding accuracy and audio output

With peak power handing of 210 watts, the GTO8608C is fearless. It also delivers accurate highs and lows, realistic sound, nothing over- or under-emphasized. The frequency response is 50Hz – 21kHz, with a 92dB sensitivity rating.

JBL I-Mount™ for easy installation

The I-Mount™ (patent no. 5,859,917) tweeter-mounting system allows easy and versatile installation of tweeters in each of the component systems. It includes a flush cup and surface-mount mounting hardware. With a 1-3/4” cutout and a 1"" mounting depth, installation becomes a snap. This allows the tweeter to be flush-mounted and can be angled up to ±40 degrees.

The JBL® GTO Series is one of car audio’s longest-running success stories – and offers the
best-performance in its price class. The GTO8608C component system has a patented
Plus One® woofer cone with up to 25% more surface area at work. A proprietary My-Ti™
tweeter gives increased power handling, reduced distortion. And a computer-optimized
passive crossover with tweeter level control delivers improved response in any vehicle
interior. With a peak power rating of 210 watts, the GTO8608C will add real muscle
to any car audio system. Two patented, very easy mounting options make adding it a
breeze.
